The US Open men's final was switched from Sunday to Monday for the fifth year in a row after Saturday's second semi-final between Novak Djokovic and David Ferrer was suspended because of bad weather.
Ferrer was leading 5-2 in the opening set when officials stopped the match because of high winds and announced play would not resume until Sunday because of an approaching thunderstorm.
Earlier, Andy Murray won the first semi-final, beating Tomas Berdych 5-7, 6-2, 6-1, 7-6.
